Title: Ventilation, heating and dehumidification in swimming pools - producing maximum heat recovery, using minimum energy for heat transfer
Inventor: DUPUY BRUNO
IPC: F24F5/00
Filed: 1975-08-19
Abstract: Method of ventilating, heating and dehumidifying swimming pools is carried out by replacing the air during opening hours in variable proportions according to hygiene and dehumidification requirements. The heat in the air which is drawn off is completely or partly recovered before being expelled with a heat pump for heating the room, while the air in the room can be completely circulated during closing hours, using the heat pump for dehumidification. Air entering the room successively passes through two or more heating batteries arranged in series and associated with different thermodynamic machines, while air leaving the room successively passes through the cooling batteries. The heating batter upon which air entering the room first impinges belongs to the same thermodynamic machine as the second cooling battery upon which air leaving the room impinges.

Title: Constant current or voltage generator - employs field effect transistor with resistance chain to determine current or voltage level
Inventor: DELAHAYE FRANCOIS
IPC: G05F3/24
Filed: 1976-03-19
Abstract: A constant current or voltage is obtained from a circuit containing field effect transistors and using a series resistance chain to determine the output level having a low temperature coefficient and good stability. Three current injection circuits each comprising three field effect transistors (T) are connected in parallel so that their currents (i1, i2, i3) flow in a common resistor (P3). Two of the circuits have feedback resistors (P1, P2) which are chosen with the common resistor to provide operation within particular temperature limits. The current flows together with the current (io) from a polarising transistor (T2) through a resistor (R2) to a battery power source (Vo). The polarising transistor is connected to auxiliary transistors (T2, T'2) to provide pre-regulation of the source output.

Title: Injection syringe for repeated use with throwaway needle - dispenses variable dose drawn from large reservoir bottle (SW 3.10.77)
IPC: A61M5/20
Filed: 1977-03-03
Abstract: The Parent Patent describes a suction injection system with metering devices operating on the throw-away principle, in which the skin of the patient is drawn up into the injection syringe and then the needle is advanced to penetrate the skin and carry out the injection. In this addition a relatively large vol. of the medicament is contained in a storage bottle. This supplies, via a duct, a valve cone inside the metering piston, within a cylinder. The length of stroke of the piston and thus the size of dose is determined by an adjustable postion of the sleeve using pins (not referenced) in screw adjustment rings outside the appts. The last movement of the guide sleeve actuates a plunger, and this actuates a plunger of a ventilating valve, thus breaking the vaccum and releasing the syringe from the skin of the patient. Used part. for medication of diabetic patients, using a relatively large reservoir of fluid.
